Paid or sponsored ads usually charge you for a click, while SEO doesn’t require you to pay for impressions or clicks. But do keep in mind that quality SEO isn’t exactly free. Depending on the target market you are in, you will have to invest time and money into getting the desired results. And if you’re not an SEO expert, then you would have to work with a reputable SEO company do it for you.
If both page are closely related (lots of topical overlap), I would merge the unique content from the lower ranking article into the top ranking one, then 301 redirect the lower performing article into the top ranking one.
